Application tiled September 16, 1880.

To all/whom it may concern:

i Be it known that we, CARL ScHLrMP, re-

siding at Vienna, in the Empire of Austria, and a subject of the Emperor of Austria, and

RUDOLF HoNzlK, residing at Schattau, in the Empire of Austria, and a subject of the Emperor of Austria, have invented an Improvement in Kilns for Burning Brick, Pottery, &c., of which the following is a specilication.

1o Figure lis a horizontal section of our improved kiln. Fig. 2 is a vertical section, on an enlarged scale, taken on the plane of the line A B, Fig. l. Fig. 3 is a vertical section taken on the plane of the line G D, Fig. l. Fig. 4is` I5 avertical section taken on the plane of the line E F, Fig. l; and Fig. 5 is a vertical section on the line G H, Fig. 1.

This invention relates to a new furnace or kiln forburning articles of pottery, earthenware, artificial basalt, and the like; and it coilsists in the peculiar arrangement of a series of connected chambers and of the draft-passages leading to and joining the same, all the parts being so arranged that the chambers can be heated by gas, which iiows into the kiln in one direction, and is joined by currents of air tlowing in the same direction, the products of combustion being carried from chamber to chamber, so that the heat in the several chambers is graduated to admit of a successive filling and emptying of the chambers, and ot a consequent continuous use of the kiln, all as hereinafter more fully described.

1n` the drawings `(particularly in Fig. l) it is shown that the kiln is divided into series of chambers, six being shown in the drawings 5 but a greater numbermay be employed. These chambers are placed in two rows, the chambers K', K2, and K3 being in one row and the chambers K4, K5, and K6 in another row, parallel to the rst.

The gas for heating the chambers is supplied to a passage, Gr, which extends through the middle of the kiln, between the rows of chambers, and from which upright lues .fr lead into cross or transverse passages, (marked 10, 1', 12, 13, 14, 1 5, 1G, and 17,) which passages are placed j alongsideoi` and between the chambersthat are in each row, so that each of said 5o chambers will beilanked by two such passages,

(No model.)

as is clearly indicated in Fig. 2, which figure also shows that said passages 101', &c., are on a level about with the top ot each chamber. The openings leading from the passage G through the several tlues x into said passages 1 1, 850., can be closed by suitable valves or gates, which are marked n n v2 n3 o4 05, o6 117 in the drawings, and which can be opened from above, and serve to regulate the iiow of gas to the several chambers.

From each passage l0 1', &c., extend downward small tubular passages b, which terminate at their lower ends in branching horizontal passages c, that lead into the several chambers K6 K5, Sto. Each passage b can be closed 65 from above by a valve, w, so that the flow of gas from each channel or passage 10 1, 85o., into the chambers can again be regulated with great nicety. IThose passages, 1512, 15, and 16, which are between two chambers supply the 7o gas by alternate tubes b to the two chambers at their sides, as is clearlyindicated in Fig. 2.

The horizontal channels c leadinto the mixing-chambers d, which are galleries anking the sides ot' the chambers Ki K5, dac., the up- 75 per walls of the galleries being made with small perforations, as shown at y in Fig. 5, so that many jets ot' gas will escape into each chamber through said openings y.

In the galleries d the entering gas meets the 8o stream of hot air which enters the bottom of each gallery d through openings kand Z, (see the lower part ot' Figs. 5 and 2,) and which, entering such gallery el through such passages k and Z, has ample opportunity to :mix within the perforated gallery thoroughly with the gas, so as to enable the gas to burn perfectly as it enters each ofthe chambers. The iiame of the burning gas traverses the chamber from f top to bottom with equal intensity, and passes 9o oft' through openings e, that are in the bottom ot' each chamber and lead into a lower passage, f. From f the products ot" combustion are conducted into passages g, `(see Fig. 5,) whence they low intoa still lower passage, i, the entrance to which is covered by an adjustable valve, h, and from the passage t' they pass through and into the passages k, and thence into passages l, that join the gallery d of the next chamber, which chamber said pro- :too

ducts of combustion traverse from the upper to the lower end, thereby heating said chamber. In other words, by the arrangementjust described the gas which enters one of the chambers K', and which burns in said chamber, has its products of combustion carried thence into the chamber K2, thence into K3, Src., if desired, so that when they enter the third or fourth chamber they will still be warm enough to be useful in keeping the chamber warm for thenishing or gradual cooling operation; but whenever the products of combustion are to be tinall y discharged it is only necessary to open valves u, (see Fig. 5,) that cover branches of the passages f, and thereby allow the escape of the products of combustion into the passage R, that leads into the chimney.

The air, needed to support combustion is carried into those chambers K' K2, Ste., which are being filled with material to be burned through doors in the ends of said chambers; but these doors, as soon as the chambers are -to be forewarmed, must be closed by masonry and remain closed until the contents of the chamber have been burned, or at least until the same are to be cooled. The cold air enters a chamber through the open door O6, passes downward through the bottom openings, e, into the passagef, thence into the passage t', to the upright iues 7s of the next adjoining chambers, which it traverses from top to bottom, becoming gradually more and more heated, and reaches, nally, through the next series of channels 7c, in a very heated condition, the mixing-gallery d of the chamber, which is actually red, and here becomes mixed with the generator-gas that enters said chamber, passing, together with said gas, through the perforations of the gallery d, and assisting, by being so thoroughly heated, in the thorough combustion ofthe gas. Thus it will be seen that the air passes through the furnace or kiln in the same direction as the gas, and that the opening of a chamber does not interfere with the proper function of the gas-chambers, but, on the contrary, insures the requisite supply of atmospheric air to the flames.

In order to more clearly define the operations of our kiln, we will now describe how the same is used, and assume that the chamber K', Fig. l, has just been tired,and that the ring therein has been completed, and that the gas-supply valves w,leadin g to K', have, consequently, been closed. In this case the chamber K2 has been warmed to a suitable degree by the products of combustion that have passed through it from K' into K3, so that the contents of the chamber K2 are already in a red heat. Now, upon opening the gas-valves e and the smaller gas-valves w, that control the inow of gas into the 4chamber K2, the gas will be let into thegalleries d of said chamber, and will there meet the hot air coming from the chamber K', and become ignited into a violent flame at the entrance into the chamber K2, which it will traverse from top to bottom.

The discharge-openings e at the bottom of the chamber K2 are so equallydisposed as to Vinsure the equal heating of the chamber and to prevent unequal drafts in different parts thereof. Through these discharge-openings the products of combustion pass to the channel j' below. Now, in order not to waste the heat contained in the gases that enter this channel f, said gases are not allowed to escape into the chimney-tine It at once, but, on the contrary, they are conveyed by opening valves h into the\passage t' below, whence they reach the chamber K3 through the proper passages la l, and serve to heat said chamber K3. The heated gases then traverse the chamber K3, escape from it through the openings e, and can now be conducted into the chamber K4, if desired, which they serve to warm. From K4 these gases, which by this time are considerably cooled, are allowed, after having traversed the chamber K4, to escape into the chim- Dey-flue R. The supply of air for maintaining combustion in the instance just given is insured by opening the door 06` of the chamber K3, which chamber contains pottery in process of cooling. The chimney-valve n beneath the chamber K4 being open, a draft is created, which causes the air that enters the chamber K6 to pass down through the openings e into the passage f below K3, thence into the passage 1T below, and from said passagez' into the chamber K', through the vertical branches kl of said passage t'. The air entering K' becomes very much heated, and passes thence into the chamber K2, where it assists combustion in manner already described.

The combustion is perfect, not only because of thehigh temperature of the air brought into contact with the gas, but also because of the thorough mixture of such air with the gas, for every gas-opening c corresponds with anair- IOO opening, l, as is indicated. onfthe right-hand side of Fig. 5. and such openings meet at the bottom of each gallery d, which galleryaft'ords sniicient room for the gas to expand and to `become thoroughly mixed with'the air.

By means of the valves above'mentioned the supply of gas and air and the passage of the products of combustion can be regulated with great nicety. By having a series of IIO IIS

valves, w, regulating the supply of gastoeach chamber, it is possible duringthe process: of burning, when it appears that at one partl of the chamber the goods are being overheated, to reduce the heat at that part by more or. less closing the corresponding valve w.

The example above given assumes that the chamber K6 is being cooled or lled,.K' just burned, K2 in process of burning, K3 and K4 forewarmed, and K5 just filled with goods.

It is better to arrange seven to eight cham.

bers in a row, as thereby more time is given for cooling, and laborers are thereby not exposed to excessive heat in removing and replacing the goods.

The letter M in the drawings shows a part of the furnace for generating the gas-g', g2,

and g3 being the grates, and a' a2, lSrc., passages that carry the gas into the passage G.

We'claiml. In a kiln for burning articles of pottery 5 and the like, the combination of the chamber K6 with the gallery d, passages c b, valves w, passage 17, valve o7, and passage G, all of said passages regulating the supply of gas, and with the passages lc l, which extend into the l Io bottom ofthe chamber K6 from one of the adjoining chambers, and with passages ef, that lead from the chamber K6 into the other adjoining chamber, substantially as described.

2. The combination, in the wall of the chain- 15 ber K6, of the passages k Z and passages c with thegallery d, all arranged so that the gas and air openings enter said gallery, substantially as described.

3. In a kiln for burning articles of pottery zo and the like, the burning-chamber K6, coinbined and constructed with a gallery, d, having perforations y, said gallery conhmunicatin g with the gas and air supply openin gs, and forming a mixing-space,substantially as described.

4. lua kiln for burning articles of pottery z 5 and the like, the combination of one burningchamber having gas and air inlet openings at the upper part with lower discharge-openin gs,

e, passage j', valve h, lower passage, t', upright passagesk l, and with the adjoining vburning- 3o chamber, into which said passages klconduct the products of combustion or air, substantially as herein shown and described.

In testimony whereof we have signed our naines to this specification in the presence of 35 two subscribing witnesses.
